I'm at 760% and donuts are starting to build up easy. I have about 2-3 million cash at times. I started too late and don't have any house farms. I noticed at 600% it started getting easier with kem farming. I still do and have about 2700 donuts at this point. I don't have all the game premium items by far but a good amount of them. I am at the point where I can buy all the premium items in each event and don't have to bat an eye. I prob make close to 100 donuts a day. I'd say it would be at least double what I have if you don't have any house farms. I started at the last week of the monorail event about 22 months ago. Oh and collider is on 24/7
